[FileCheck] Provide an option for FileCheck to dump original input to stderr on failure The option can be either set using environment variable (e.g. env FILECHECK_DUMP_INPUT_ON_FAILURE=1 ninja check-fuzzer) or with a FileCheck flag. This can be extremely useful for debugging, cf. https://groups.google.com/forum/#!topic/llvm-dev/kLrzg8OM_h8 for discussion. Differential Revision: https://reviews.llvm.org/D49328 llvm-svn: 337609
